  1. 1. Extraction of tool reaction forces using LS-DYNA and its use in Autoform sheet metal forming simulation

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Esbjörn Zachén; [2019]
    Keywords : Sheet Metal Forming; Stamping Die; blank holder; Structural Analysis; Finite Element Simulation;

    Abstract : In product development there is still potential to decrease lead times with faster and more accurate simulations. The objective of this thesis was to study whether Finite Element (FE) simulations using explicit LS-DYNA to extract reaction forces from sheet metal forming tools during forming, could be used to improve existing FE models in sheet metal forming software AutoForm.

  2. 2. Production and processability for future square shank tool holders

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik; Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Filip Rudbratt; Martin Wretlind; [2018]
    Keywords : Production; Processability; Tool holder;

    Abstract : The square shank tool holder is one of Sandvik Coromants most common products. The tool holder has been manufactured the same way for 25 years without changing tolerances. However, it is predicted that tighter tolerances will be required in the future to maintain competitiveness. READ MORE

  3. 3. Press Measurements and Virtual Rework of Stamping Dies

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik; Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Einar Palsson; Mårten Hansson; [2017]
    Keywords : Virtual Rework; Inverse Modeling; ARAMIS Digital Image Correlation DIC ;

    Abstract : Stamping dies are used in the Sheet Metal Forming (SMF) process for manufacturing of car body parts. The lead time for design and manufacturing of a stamping die is long, and therefore costly. READ MORE
